Greenlee 51046520 – Frequently Asked Questions
1) What size hole does the Greenlee 51046520 die punch?
The 51046520 is a 3-1/2 inch conduit size die, meaning it cuts the 4.000 inch (102.700 mm) round knockout that 3-1/2 inch trade size conduit needs. The conduit trade size and the actual hole diameter are different numbers, so if you are working from a hole diameter on a drawing, match it to the 4.000 inch figure, not the 3-1/2 inch name.
2) Will this Greenlee conduit die work with my existing knockout punch driver?
It is built for a 4.000 inch standard round knockout punch unit, so it mates with standard round knockout punch tooling at that size. It is a die only, part of a punch and die set, not a complete punch assembly with a draw stud or ram.
3) Is the Greenlee 51046520 a complete knockout punch kit or just the die?
Just the die. The 51046520 covers the die half for a 4.000 inch standard round knockout, so you supply the matching punch, draw stud and driver (hydraulic, battery or manual ram) yourself. Order the mating punch for the same 4.000 inch hole or the set will not cut.
4) How big is the Greenlee 51046520 die and will it fit in my tool case?
Packaged, the 51046520 measures 7.400 inches long by 6.700 inches wide by 4.700 inches high, about 233 cubic inches of space. Plan a slot in the punch case rather than a pouch, since large-diameter dies like this one are bulky next to the small conduit sizes.
5) Is the Greenlee 3-1/2 inch conduit die made in the USA?
Country of origin on the 51046520 die is the US, which matters on federally funded and Buy American jobs where tooling origin gets documented alongside materials.
